ARCHIE C. CUMMINS, OF LONGMONT, COLORADO.

CHAIN-CONNECTOR.

Application filed March 24, 191 6.

T 0 all whom it may concern Be it known that I, ARCHIE C. GUMMINS, acitizen of the Un1ted States, resldmg at Longmont, in the county ofBoulder and,

State of Colorado, have invented certain new and useful Improvements inChain-Connectors; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention has for its object to provide a simple and effectivedevice primarily designed for detachably connecting the opposite ends ofthe side chains of anti-skidding attachments for motor vehicle wheels.

Another object is the provision of a connector embodying a novel type ofguard, and means for retaining the guard in adjusted position withrelation to the connecting element.

Vith these and other objects in view, the invention consists in thenovel construction, combination and arrangement of parts as will behereinafter specifically described, claimed and illustrated in theaccompanying drawing, in which:

Figure 1 represents a plan view of the improved chain connector, Fig.2represents a longitudinal sectional view therethrough, Fig. 3 representsan enlarged detail sectional view therethrough, and Fig. 4 represents adetail sectional view on the line 4l of Fig. 1.

Referring to the drawing in detail, wherein similar reference numeralsdesignate corresponding parts throughout the several views, the numeral5 indicates the connecting plate of the connector, which is preferablyof flat elongated formation and provided at one end with an aperture 6,receiving a pin or rivet 7 whereby the link at one end of a chain 8 ispermanently attached to the plate 5. One longitudinal edge of the plate5 adjacent the end opposite the aperture 9 is formed with a pair ofspaced and substantially L-shaped recesses 9, the inner extremities ofwhich are directed away from the aperture 6 and are of such size as toreceive the link at he opposite end of the chain 8.

Specification of Letters Patent.

Patented Oct. 3, 1916.

Serial No. 86,432.

A hollow sheet metal guard 10 is slidably mounted upon the plate 5 andis formed adj acent one end with longitudinal slots 11 receiving therivet 7. The longitudinal edge of the guard 10 overlying the recessededge of the plate 5 is formed with inwardly ex tending slots 12, whichwhen. moved into registration with the parallel portions of the recesses9 permits of the insertion or removal of the chain link 8, but, whenmoved in the opposite direction, to the position illustrated in Fig. 1,the portions of the guard lying adjacent the slots 12 overlie the mouthor throat of the recesses 9 and thereby prevent accidental removal ofthe chain link from the connector.

Intermediate the innermost recess 9 and the aperture 6 the connectingplate 5 is formed with a transverse recess 13, receiving a shank 14,carrying a pair of eccentrically arranged heads 15. The heads 15 are ofcircular formation and are rotatably mounted in correspondingly shapedapertures 16 formed in the opposite sides of the guard 10, and areformed with diametrical slots 17 adapted to receive the blade of a screwdriver or other suitable tool, whereby the adjusting element may berotated to effect the desired adjustment of the guard 10 with relationtothe connecting plate 5. It is further evident that the adjustingelement if snugly fitted. in the guard 10 and plate 5 will effectivelyretain these elements in their adjusted position.

What I claim is:

1. A chain connector including a plate adapted for pivotal connectionwith one end of a chain and having L-shaped recesses in one longitudinaledge thereof adapted to receive the free end link of the chain, a guardelement slidably receiving said plate, a shank rotatably mounted in saidplate and eccentrically arranged heads carried by said shank rotatablymounted in said guard element for adjusting the latter with rela tion tosaid plate.

2. A chain connector including a plate adapted for pivotal connectionwith one end of a chain and having L-shaped recesses in one longitudinaledge thereof adapted to reel e the free end lin of said. h Said,

plate having a transverse recess therein, a guard element slidablyreceiving said plate and adapted to overlie the outer extremities of theL-shaped recesses to prevent removal. of the chain link therefrom, acrank rotataelement for adjusting the latter longitudinally of saidplate.

In testimony whereof I afiiX my signature in presence of two Witnesses.
